Vektrex designs and manufactures high-performance LED/VCSEL/LIDAR test solutions for leading manufacturers and standards labs worldwide. See this page to preview a comprehensive listing of videos made by Vektrex to help you better understand your current source.
Easy Light Measurement System Upgrade
Light measurement system upgrades are easy using Vektrex products. In this video, we show you how to easily integrate the Vektrex SpikeSafe Source Measure Unit featuring the new Force Sense Selector Switch into your existing test setup – whether you’re using a Keithley 2400, 2600, or any other source meter or specialized instrument.
How to Generate an IV Curve Using the SpikeSafe SMU
With the SpikeSafe SMU, a pulsed source measure unit, it is easy to benefit from “crazy stable” measurements. In this video, you will learn about Generating a High Power IV Curve using the SpikeSafe Pulsed Source Measure Unit.
Watch “How to Generate an IV Curve Using the SpikeSafe SMU” on YouKu.
Use a Source Measure Unit for “Crazy Stable” Measurements
Vektrex claims the SpikeSafe Source Measure Unit produces “crazy stable” measurements. In this video, we compare the voltage measurements of the Vektrex SpikeSafe SMU’s internal digitizer with those of the Keithley DMM7510 on the same load – paying close attention to the stability of the entire Vf pulse capture from each unit.
Improve LED Light Measurements
3 Steps to Improved LED Light Measurements – Part One: Power
Providing sustained power is the first step to improving your LED light measurements. Watch part one of Vektrex’s new webinar series by Jeff Hulett, creator of the SpikeSafe current source.
Watch “3 Steps to Improved LED Light Measurements – Part One: Power” on YouKu.
3 Steps to Improved LED Light Measurements – Part Two: Accuracy
Once you have the capability to use all three methods, the question becomes: which method will yield the most accurate measurements? Vektrex engineers conducted an L-I sweep with one LED using each of the three methods.

High Power Pulsed Sources
Compare Powering 25W COB with Vektrex Performance Series Current Source and Keithley Source Meter
See a 25W COB powered with a Keithley Source Meter and a Vektrex SpikeSafe Performance Series Current Source in this video.
Pulsed Power Comparison – Vektrex SpikeSafe Current Source or Keithley SMU?
Some current sources and source measure units provide their maximum advertised power in a limited pulse width range, making them useless for the aforementioned test methods.
Performance Series Current Sources
What’s new with Performance Series Current Sources?
In 2017, the Performance Series won a Sapphire Award. We’ve spent the last year making them even better.
